I have had a similar experience. I tried moving about 40,000 emails to a folder
and aconadi imap process went to 100% CPU for the next 16 hours until I got
annoyed with the fan noise. However stoppiing aconadi, moving
agent_config_akonadi_imap_resource_0_changes.dat, and starting aconadi again
fixed it. Though not all of the emails seems to have actually moved to the
folder.

I was bitten by this bug too. The problematic file was
agent_config_akonadi_imap_resource_0_changes.dat

After applying the suggested workaround (stop akonadi, rename the file, start
akonadi), the issue went away.

this is on 

Akonadi 4:19.04.1-0xneon+18.04+bionic+build25

I had the same problem as Patrizio, and using the workaround by Tomasz (comment
4) fixed it completely on my Tumbleweed.

After I was hit by https://bugs.kde.org/show_bug.cgi?id=373782 and could "fix"
that with the sql_mode change I also got 100% CPU for these agents on KDE neon
User Edition 5.8:

- Notes Agent
- Migration Agent
- Archive Mail Agent
- Mail Dispatcher Agent

Removing the corresponding
/home/user/.config/akonadi/agent_config_akonadi_*_agent_changes.dat files help
for me too. The 4x 100% CPU symptom is gone and mails are sent again.

@Laurent: Sorry for the late reply. As kMail did not work for me any more with
this bug, I had to switch to Thunderbird for the meantime - and I did not
notice that I had not subscribed to the IMAP folder where my KDE Bugzilla
notifications end up, so I missed your question... :-(

(I configured kMail to show all folders regardless of subscription state.)

So that I've now seen your question (and tons of others) is an indication that
it's working for me again since yesterdays update. :)

Interestingly, KDE PIM Runtime which contains the mail agent was not changed
during this update, but Akonadi was upgraded to
4:16.12.0+p16.04+git20170104.0343-0 (KDE Neon package).

So if this fix was contained therein, it helps. If it wasn't, the issue was
caused by something else.

I can confirm Tomasz's solution fixes the problem on openSUSE Tumbleweed. I
only noticed the problem when KMail failed to send my messages in my outbox,
presumably because of the saturation of the CPU processes.

Thanks for the suggestion.

There is a fix for 100% CPU in akonadi master
98e72dd81f3b8d5faeb262f765cda9539d1c271f

Are you able to rebuild akonadi with this patch ?

Can you fix it:
lsof -p 

Example return:
...
akonadi_m 3035 user   10r  REG8,3  324 3807516
/home/user/.config/akonadi/agent_config_akonadi_migration_agent_changes.dat

- stop akonadi,
- rename file agent_config_akonadi_migration_agent_changes.dat
- start akonadi

The same for the other akonadi process (100% CPU)
